North Houston Highway Improvement Project (NHHIP)

A growing, opportunity-rich greater Houston should provide safe travel. Parts of the I-45 corridor have not changed since first constructed over 50 years ago, and the roadway’s configurations do not meet federal safety standards or current and future traffic demands. The North Houston Highway Improvement Project (NHHIP) is TxDOT’s $7.9 billion investment to redesign I-45 in three segments from US 59 to Beltway 8 North. The I-45 improvement project not only brings these highways up to current standards, but also alleviates congestion, enhances safety, expands transit options, and addresses flood mitigation and disaster evacuation needs. 

About the Project

NHHIP is TxDOT’s $7.9 billion investment to redesign and rebuild I-45 near downtown Houston from US 59 to Beltway 8 North. The project will create additional roadway capacity, incentivize public transit usage and ridesharing through the creation of 24/7 MaX lanes for transit and high-occupancy vehicles, and improve the overall mobility and operational efficiency of the I-45 corridor in and around Downtown Houston. 

The North Houston Highway Improvement Project (NHHIP) is a once-in-a-generation opportunity to help the Greater Houston region’s infrastructure catch up with decades of growth and ensure we are prepared to safely move even more people and goods anticipated in the coming decades.

The Federal Highway Administration (FHWA) halted progress on the project in June to review the project’s environmental impact statement. We support a thorough and timely review and will work with state and local leaders to resolve any outstanding issues with the FHWA by November 30, as outlined by TxDOT, to move this transformational project forward.
